Revealing planktonic ultrastructural diversity with Expansion Microscopy (ExM)

We are joining the EMBL TREC (Traversing European Coastlines) expedition in 2023 and 2024!
As part of an international EMBL-EPFL-UNIGE team (Dey, Schwab, Saka, Hamel, Guichard), we are coupling expansion microscopy (Cryo-ExM and U-ExM) to 18S FISH for species ID and sub-cellular imaging. We aim to create an atlas of native eukaryotic cellular biodiversity with unprecedented 3D spatial resolution, with a long-term view to assess the repercussions of climate change on free-living microplankton populations.

We are also using this opportunity to isolate & culture new Ichthyosporeans!
